Glazing and Insulation Selections

Duraseal® Spacer

This is our standard spacer. Duraseal takes optimum advantage of laminates and adhesives to reduce thermal conductivity while improving surface and corner appearance over other insulating glass spacers. This multi-layered spacer system featuring specialized components results in superior window performance and aesthetics over other warm edge spacers. Test results performed by a third party validate the superior thermal performance benefits of Duraseal when compared to other spacers.

LoE² Glass

A coated glass that reflects radiant heat rays. LoE² glass will help keep heat in or out, while allowing light to enter and brighten your home. In the summertime, LoE² reflects the heats rays back outside to keep you cool; during the winter it holds the sun's rays indoors to keep you warm.

Argon Gas

Argon Gas acts as an acoustic insulator and has an insulation value much higher than air. Argon is used to boost the benefits of LoE² glass, the increase in thermal performance gas filling without LoE² provides is pretty small. Argon Gas inhibits radiant heat transfer and sound waves. Argon is an inert (inactive) gas, sunlight stable, non-corrosive, nontoxic, chemically inert to UV radiation, as well as being odorless and colorless.

Triple Pane Energy Savings Glass

Almost 4 times the insulation of a clear insulated unit, the Thermal Line Energy Saving Glass (ESG) works in the winter by reflecting heat back into the room. In summer, it rejects the sun’s heat and damaging UV rays. In fact, all but 5% of the UV rays stay outside while dramatically reducing summer air-conditioning needs. Enjoy all your house year-round with Energy Saving Glass from Thermal Line Windows - keeping your home comfortable, year-round.

Trigon Gas Blend (Triple Pane Units Only)

Note on Gas Retention: All gases will, over a significant period of time, leak from the insulated glass even without a seal failure, slowly decreasing its benefits.
